To all whom t may concern tain new and useful lmproveinents in Machinesfor Pressing Heel-Lifts, Heels, Sac.,l

. and 6-are plan of which the following is a specification.

This invention relates to machines adapted yfoi` compressing heel lifts,other articles, and particularly for produc-` heel, Shanks, and

ing the pressed vand ornamented toplift shown in the patent to W. F.Bostock, No.V

907 ,7 23, dated December 29, 1908. In carrying this object into effectI provide a inachine having pressing dies formed, adjusted and operatedso as to impart the necessaryl degree of pressure to a toplift or acomplete heel, and to impress at the same time the ornamentalconfiguration illustrated in the patent above-noted.

In addition to the above, ity is my 'object to provide in a machine ofthis character an automatic carrying mechanism for carrying lifts orheel blanks from the operators station in front of the machine to thepressing position between the dies, and' after the lifts or otherarticles have been pressed, to carry them from the pressing positioninto a discharging position.

pressing machine of this general nature side blocks adjustable so as toclosely embrace pressure to the edges of the article sufficient 1orconnecting rod l1 and toggle levers l2,

to condense it.

In the accompanying drawings I have.

illustrated a machine in which the objects of my invention and theprinciples thereof are carried into effect inthe best manner at presentknown to me, it being understood that the machine as there shown and asreferred to.

f Thedie 16 or movablepresser is carried bythe cross-head 8 andreciprocated toward and from the fixed die. Y Said die 16 is the blockyieldingly held by the. cross-head 8, preferably by being secured Aupona stem 22 which is Ysupported by a spring 23. The movement of the stemis limited by a pin 25 in the cross-head. The dieV 16 is held projectedby the spring 23 at all times except when pressed against a liftcontained between it and the iixed die 15. At these timesthe spring'23yields until the die 16 `reaches a plate 26 which affords a rigidabutment.` The height of this rplate is adjusted by a wedge or shim 27,which is positionedY by Va screw 28. By adjusting the wedges 2O and 27,the distance apart of the dies when in their ultimate positionsmay bevaried to accommodate lifts or heels of varying thickness and to securethe desired degree of compression.

As ythis machine is designed to form the y toplift-shown in the patentbefore referred to, or to form a heel having a similarly ornamentedtread-surface, one of the dies, as

l-ftures as noted inthe said patent. This forlthe die 16,'ismade in suchform as to produce a rsurface having the characteristic feamationof thedie is shown best in Figs. 7 and8, the central part a of the actingsurface of the VdieV being cut to produce the desired ornamentationinthe lift or heel, and

the edge portion?) being depressed to cause the surface of the lift orheel at the edge thereof'tok be raised. The relation of the dies 15-and16 to one another may, of course,

-1 be reversed, the former die vhaving the ornamented and recessedsurface and the latter being plain, without departing from the Yspirit of-my invention. Y

cr'ossehead 8, between a fixed lip 29 formed 16 and of the lift or heelthereon.

.thereon,and blocksBO, 31. The lip 29 provides a gage'or guide for-thebreast ofthe lift or heel, Vwhile the blocks 30 and 31 are recessed tofit the periphery of the die block T ese blocks thus constitute the twohalves of a divided mold which confines the periphery of theheelandprevents it from spreading when the lpressure vis applieda Y Themembers of the mold arejbrought togetherjto engage the lift when thepressure is applied and are separated when the pressure is removed, inorder to permit ready removal o'fka pressed lift and'msertionpf a unewone; The approach and recessionV of the Y parts of the mold toward andfrom one another are'c'ontrolled by` the movements of thel cross-head 8in bringing .the dies intoy and out of pressing relation. For this purfThe die 16 isfcontained in a recess in the.

pose the blocks 30 and 31 are arranged to slide upon t-he cross-head 8along the lip 29, which thus at one time acts as a guide for the blocksand as a gage for locating the breast of the heel lift.` livotallyconnected to the blocks 30 and 31, or rather to separate blocks' 32 and33 (which latter are connected to the blocks 30 and 31 by straps 34, 35)are links 36 and 37, the outer ends of which are connected respectivelyto bars 38 and39. The links are so placed that when the cross-head iselevated into its uppermost position the blocks 30 and 31 are broughttogether against the rim of the heel or lift, and as the cross-headdescends, the increasing angularity o-f the links causes the blocks tobe drawn apart. These blocks are so made that they will not condense thelift, but will maintain its original shape. Preferably the arrangementis such that when the movable cross-head is in its extremeupper-position, the links 36 and 37 are approximately in line. Thedistance apart of the blocks may be accurately adjusted and either orboth blocks shifted to center them by means which shifts the position ofthe bars 38 and 39, one such means being shown in Fig. 1. As here shownthe bars are pivoted at their lower ends to the side frames of themachine base, so that their upper ends may swing toward and from oneanother. The upper end of each bar passes into a slot in the fixedcross-head and is engaged by a screw or bolt 4:0 threaded into the armand having a head bearing against the end of the cross-head. A wedge 41is inserted between the arm and the adjacent end of the cross-head andis adjusted up or down by a screw 42. By this adjusting means thepositions of both bars and therefore of the mold blocks may be readilyand accurately adjusted. Thus the parts of the mold may be set so thatwhen nearest together they conform exactly to the original form of thelift as died from the leather, without either compressing the liftedgewise, or allowing it to spread, for it is the vobject of this partof my invention to preserve the lift after compression of the saine sizeand shape as given it by the cutting die, without either compressing itedgewise or allowing it to expand.

One of the main features of the invention is a carrier which isautomatically operated to carry blanks from the operators station intopressing position between the dies, and then to remove the lifts orheels after being compressed, and carry them into a position from whichthey may be delivered to a discharge spout. By virtue of this feature oflthe invention, the operator of the machine has nothing more to do thanmerely place the blanks in the carrier, the location of the blanksbetween the dies and the discharge of the compressed articles from themachine being accomplished by the carrier at theproper timeautomatically. The carrier consists of a head 43, from which project twoor more licei-grasping devices 44. The latter project horizontally fromj which is secured to thecrosshead on a level with the end of the die 16when the latter is projected as shownV in Fig. 2. These blank-graspingdevices 44 consists each4 of two jaws 46, 47, pivoted to the head 43 andformed at their outer ends into V.the shape of the periphery of a heel.On each jaw is fastened a segmental cheek 48, made to t accurately theheel. The 49 from which project ears 50. The jaws of each gripper arenormally'held together by a spring 51, while any movement which they mayhave is given equally to each., by means of a tooth 52 on one jaw nearits pivot, en-

gaging a notch similarly 'located on the other jaw. i f

The carrier and the grippers connected therewith are given astep-by-step rotary motion during the rising and falling movements ofthe cross-head 8, from a shaft 53, which has a like motion. A squared or`otherwise non-circular end 54 on the shaft projects into alcorrespondingly shaped opening in the head 43 so as to communicatemotion thereto. The shaft 53 is held in a bearing 55 integrally orotherwise secured to the moving cross-head 8, and a collar 56 fastenedto the shaft above this bearing causes the latter to rise when thecross-head rises. The lower end of the shaft is guided in the crossebar3 so asto be held steady, but not to be prevented from'up and downniotion. Rotary movement is given to the shaft 53 from the main driveshaft 9 through a rack 57 confined in a guide 58 `(see Fig. 1) andreciprocated by a connecting rod 59 engaged with a crank pin 60 on adisk 61, which is secured to the end of the shaft 9. This rack engages a`pinion 62, journaled in bearing brackets 63 and 64,

` which project from the side frame 2. W'ith this pinion is also engageda second rack 65 held in a guide 66, which extends transversely of themachine from one side frame tothe other. The latter rack meshes with awide-faced pinion 67 mounted loosely upon the shaft 53. This pinion issupported at its lower end by a collar 68 pinned to the shaft so that itis compelled to rise and fall with the latter. 1t is suliiciently longto remain in mesh with the rack 65 in both limits of travel of thecross-head. Secured to the pinion 67 is a pawl carrier 68a carrying apawl 69. The latter engages a wheel or disk 70 rigidly secured to theshaft which has as many notches and teeth as there are lift grippers 44,in this case four. The ratchet 7 O is formed as a flange on a sleeve 71,which surrounds the shaft 53 and is secured thereto the head over atable 45v `grippers 44fare moved step by about one half of the curvedpart of jaws` also have breast pieces asby a set screw 72.

by. any suitable means,

the racks 57 and 65 As the shaft 9 rotates,

are reciprocated, thereby oscillating the pinion 67. `This imparts astep-by-stepl rotation to the shaft 53 through the pawl and ratchet justdescribed. `Therebyithe step from the front of the machine. where the`operator stands, into a position between thev pressing dies and thenceover a discharge spout indicated by dotted lines in Fig. 4 anddesignated by the numeral 73. On the fixed cross-head are securedpointed bars 74 and 75, one directly in rear of the die 15 and the otherat the left of the machine, as shown'in Fig. 1. These bars are locatedso that their vpointed ends will enter'between the tongues orprojections 50 of those lift grippers which are located respectivelybetween the pressing dies and over the discharge spout.- rlhus thegripper which holds theblank ready for pressing is opened toadmit thedie 15, and the gripper holding a compressed lift or heel is opened topermit such. article to fall upon the and thence intoa receptacle.

From the foregoing description the operation of the machine willbereadily understood. The operator stands at the front where he canpress heel lifts.` and blanks into the gripper which'is shown in Fig. 4projecting toward the front of the table. As each gripper comes to thefront empty, the attendant places a toplift or other article in it, theupper edges of the cheeks 48 being beveled as sho-wn in Figs. 7 and 8 topermit ready insertion of these articles. In each double reciprocationof the cross-head the carrier is fed one step, thereby carrying a filledgripper over the die 16 and under discharge spout the die 15. Thismovement occurs while the dies are separated, the operating mechanismbeing timed to turn the shaft and lift-carrier `while the movablecross-head 8 is descending. As the cross-head 8 rises, the proj ections50 o-n the lft-holder at the rear engage the pointed end of the bar 74and are separated, allowing the lift to rest on the die 16 between theblocks 30 and 31'of the mold. When the lifts are brought against thefixed die, the die 16 is caused to yield against the spring 23 until itbrings up against the fixed abutment plate 26, thus allowing the lift tobe brought between the parts of the mold and allowing the latter to beclosedfupon the edges of the lift. As the cross-head descends the spring23 holds the die 16 up until the table and carrier havegripperare'again, opened, this time byl thev 'discharging' `position vbythe" intermittent feed/mechanism. lUpon the next upward travel of thecross-head 8 the jaws of this bar 7 5, which allows the lift or otherarticle Vto'drop from the. gripper and escape. t isVwithin'the-contemplation of my invention kalso to 'provide' another 'barsimilar to the bars 74 and 7 5min a position'opposite. to the latterbar, thatis at" the opposite .side of the liftcarrier and symmetricallyarranged with respect to the Ybar 7 5. Such additional bar would belocated to open the gripper sho-wn at the right-hand side of Fig. 1 andin the upperi part of YFig. 4, so that when thus.

opened Va lift or heel might be dropped be- V tween this pair ofgrippers by the attendant of the machine.

ln Fig. 13 is shown a modified formiof vgripper which is provided withmeans for taking lifts, or heels of any size. Upon the jaws 46 and 47 ofthe gripper are adjustable vfingers 461, 462 and 471, 472 respectively.

The combination in` amachine of the character described, of arelatively stationary die, a cross-head movable toward and from saiddie, a relatively movable die carried by said cross-head,yielding meanstending to project the movable die from the crosshead toward thestationary die, a wedge interposed between the movable die and thethrust-applying surface ofthe cross-head, and means `for adjusting saidvwedge to vary the possible extentofmovement, thereof relatively to thecross-head. j

27. .The combination in a machine for pressing heel lifts,`heels, etc.,of a relatively stationary die, ahead movable toward and from said die,members constituting a mold carried by said head, a relatively movabledie'carried by the head between said mold members, yielding meanstending to project the movable die out of the mold 'toward thestationary die, and permitting it to be pushed into the mold by theresistance of the article being pressed, an abutment plate looselyfitting the mold cavity under thev movable die, and an adjustable Wedgebetween said plate and the adjacent face of the wedge for limiting theextent to which the movable-die may be retracted, and thereby the degreeof pressure exerted on the article.

28. A compressing machine comprising complemental, opposed, coperatingpressing dies, one of which is movable toward and from the other, andone of which is mounted with ability to yield relatively to the other,mold members flanking said yielding die Aformed to fit about theperiphery of the article to be compressed, whereby to prevent spreadingofthe article under compression, means for carrying said movable dietoward and from the other die, an article carrier, and means forbringing said carrier between the dies when the latter are separated andcausing said carrier there to pause, the article being displaced fromthe carrier by the pressure of one die and the yielding of the otherinto the space between said mold members, and being returned to thecarrier by return of the yielding die.
